A popular department store chain wants to make computer upgrades as well as conduct a major remodeling effort to increase revenue to all their 100 stores over the next 2 years. The remodeling will occur in two phases. The two phases are required at each store and can be completed in any order, but each phase must be fully completed before the next phase can begin. Phase 1 will take approximately 32 weeks and will not require a store to be temporarily closed. Phase 2 will take approximately 20 weeks and will require a store to be temporarily closed.
In order to keep inventory level and total revenue for the department store chain at an operational level, 75% of the stores must remain open to the public at all times. Against the board of director's advice, the Chief Executive Officer (CEO) made a decision to start and complete the top 25 revenue-producing stores in the first year to get those stores remodeled and fully operational.
A business analyst (BA) has been brought in to help with planning the project and gathering requirements.
What tool will help the BA understand the changes needed to keep the majority of the stores open?
